19398197 ÷ 628 
Our goal is to divide 19398197 by 628.

Going ahead to step 1:
1 divided by 628 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 628

On to step 2:
If we divide 19 by 628, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 628

Advancing to step 3:
If we divide 193 by 628, we get 0 and a remainder of 193.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 193, we get 193.
Take the next digit (9) from the dividend and append it to 193, then repeat: 1939 / 628

On to step 4:
The number 628 fits into 1939 3 times, leaving a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1884 from 1939 and we're left with 55.
Grab the next digit (8) from the dividend, add it to 55, then carry on: 558 / 628

Step 5:
When dividing 558 by 628, we get 0 with a remainder of 558.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 558 and we're left with 558.
Take the next digit (1) from the dividend and append it to 558, then repeat: 5581 / 628

Going ahead to step 6:
When dividing 5581 by 628, we get 8 with a remainder of 557.
Write down 8 as next digit of the result. 
Result so far: 308.0
If we take 5024 away from 5581, we end up with 557.
Bring next digit (9) of the dividend behind the 557 and repeat the process: 5579 / 628

Step 7:
The number 628 fits into 5579 8 times, leaving a remainder of 555.
Put 8 as the next digit of the answer. 
Result so far: 3088.0
Deduct 5024 from 5579 and we're left with 555.
Append the next digit (7) from the dividend to 555 and continue with: 5557 / 628

Going ahead to step 8:
5557 divided by 628 is 8 with a remainder of 533.
Use 8 as the next digit of our solution. 
Result so far: 30888.0
Subtracting 5024 from 5557 leaves us with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Step 9:
5330 divided by 628 is 8 with a remainder of 306.
Record the quotient 8 as the next digit in the result. 
Result so far: 30888.8
Subtract 5024 from 5330 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 10:
If we divide 3060 by 628, we get 4 and a remainder of 548.
The next digit of our result is 4. 
Result so far: 30888.84
Subtracting 2512 from 3060 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Moving on to step 11:
If we divide 5480 by 628, we get 8 and a remainder of 456.
Write down 8 as next digit of the result. 
Result so far: 30888.848
Subtract 5024 from 5480 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 12:
628 can be fit into 4560 7 times, resulting in a remainder of 164.
The number 7 becomes the next digit in our result. 
Result so far: 30888.8487
Deduct 4396 from 4560 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 13:
1640 divided by 628 is 2 with a remainder of 384.
Put 2 as the next digit of the answer. 
Result so far: 30888.84872
Subtracting 1256 from 1640 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 14:
628 can be fit into 3840 6 times, resulting in a remainder of 72.
The next digit of our result is 6. 
Result so far: 30888.848726
Deduct 3768 from 3840 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 15:
If we divide 720 by 628, we get 1 and a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 30888.8487261
The remainder is 92 after subtracting 628 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 16:
When dividing 920 by 628, we get 1 with a remainder of 292.
The number 1 becomes the next digit in our result. 
Result so far: 30888.84872611
Subtract 628 from 920 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

The final outcome is 30888.84872611, with a leftover of 2.92e-07.
